Richard Ding updated PIG-3000: ------------------------------ Description: In this Pig script: {code} A = load 'data' as (a:chararray); B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV') ? 1 : 0); } {code} The Eval function UPPER is called twice for each record. This should be optimized so that the UPPER is called only once for each record was: In this Pig script: {case} A = load 'data' as (a:chararray); B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV') ? 1 : 0); } {case} > Optimize nested foreach > ----------------------- > > Key: PIG-3000 > URL: https://issues.apache.org/jira/browse/PIG-3000 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.10.0 > Reporter: Richard Ding > > In this Pig script: > {code} > A = load 'data' as (a:chararray); > B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV') > ? 1 : 0); } > {code} > The Eval function UPPER is called twice for each record. > This should be optimized so that the UPPER is called only once for each record -- This message is automatically generated by JIRA.
